What is the fire rating of American Olean 8×8 floor tile?
Tile itself does not have a fire rating, it is the entire floor or wall system, which means the tile plus substrate that is fire rated. Tile is fire resistant, as the majority of tile requires approximately 2,000 degrees before heat would have any affect on either the bisque or the glaze. However, ceramic tile by nature will transmit heat. For this reason, if the substrate is combustible, it will downgrade the rating. The Tile Council Handbook, section titled “Fire Rated and Sound Rated Walls,” provides explicit details on what substrate should be used to obtain a one and two hour fire rating.
